I have a array declared as: char* arrs[20][30]; I have filled up this array with name and value and now I must compare for example, the first element of arrs [] value and the third element of arrs[] value. How can I do this?

I have tried to use strcmp and have also tried (arrs[0] == arrj[1][8]) with no luck. My goal is to check if the corresponding values are equal. (for reference: arrs[0] = freq :100kHz and arrj[1] = freq: 100kHz). I just wanted to see the values are e...

STM32L452CC and STM32L4Q5CGU6, issue with USART

My colleagues went to my office and reported that the STM32L452CC with the USART interface (5MHz and 10MHz) was working fine but had to use STM32L4Q5CG due to stock usage, but it failed at 10MHz but working fine 5MHz.I have explored errata, datasheet...
